Support for Capital Punishment

On Thursday in POLI 1100, a general discussion about the distinctions between democratic and non-democratic regimes focused on the use(s) of violence by governments as a means of control. This led to a discussion of the use of, and support for, the death penalty. As many of my students knew, the death penalty is not used in Canada or Europe (with the exception of Belarus) but is used in the United States. Most of the class, however, was surprised to learn that, despite the differences in policy, until quite recently a majority of both Canadians and Americans supported the death penalty. The graphic below shows the supports of a Gallup-Ipsos survey carried out in 2004, in which Canadians just barely oppose the death penalty (although, as you can see, it is not a majority), while Great Britons (55%) and US Americans (64%) both have majorities supporting the death penalty.

Although support for capital punishment is decreasing in many countries, in many European countries a majority of the population still is in favour of the death penalty for those convicted of murder. What about Japan? In a poll released in February 2010, a record 85% of Japanese supported the death penalty!

What do you think about these results? Are they as you expected? What does this say about the political culture of the countries in question?
